Does an ECVT Need Transmission Fluid Replacement?
2 Answers
An ECVT does require transmission fluid replacement. Additional information about transmission fluid is as follows: 1. Any type of fluid has a shelf life and needs to be replaced after a certain mileage or period of use. 2. Due to special driving conditions and external environmental factors, the transmission fluid in a car will degrade over time, necessitating regular replacement. 3. Transmission fluid serves to transmit hydraulic power and provide cleaning and lubrication. If the transmission fluid is not replaced for an extended period, the fluid particles may enlarge or generate debris, blocking the fluid passages and potentially causing transmission malfunctions. Therefore, transmission fluid must be replaced periodically.
I've researched this issue extensively, and eCVT transmissions do require regular transmission fluid changes. Although manufacturers often advertise them as maintenance-free, from a mechanical perspective, transmission fluid is as vital as blood in the human body. Think about it - planetary gears, clutch plates, bearings and other metal components inside the transmission are constantly operating under high-speed friction. In high-temperature environments, the fluid's performance gradually deteriorates. Personally, I change it every 4 years or around 60,000 kilometers, which only costs about a thousand yuan. The consequences of long-term neglect include increased noise, gearshift jerking, or even bearing failure - repairs would cost far more than this maintenance. Especially for hybrid vehicles with frequent start-stop cycles that place greater stress on transmissions, regular maintenance is absolutely essential.
